The Kingdom Is Home to the Middle East's Biggest and Most Liquid Market

DUBAI—Saudi Arabia plans to open its $530 billion stock market to foreigners for the first time early next year, a move that will allow the Middle East's biggest economy to attract more international investment and reduce its dependence on oil revenue.

The kingdom is among the last of the big markets to limit international access, but it was expected to open the doors to foreign cash while it rolls out plans to spend hundreds of billions of dollars to build infrastructure and provide employment across the country.
